Answers

The expanded form of the given logarithms ( log 4 s⁴ t) is =  2log(2) + 4log(s)  + log(t).

Property of logarithms:

The features of the log are used to increase a single logarithm into numerous logarithms (or) compression multiple logarithms together into a single logarithm. A logarithm is simply another way of writing exponents. Thus, logarithm properties are obtained from exponent properties.

According to the given data:

log (4 s⁴ t)

can be written as log (4 s⁴ t):

Property used in the solving (log b*c = log b  + log c) and (log ₐᵇ = b log a)

write an equation of the line passing through points (-2,-6) and (4,6)

Answers

Answer:

your equation is Y = 6

Step-by-step explanation:

Use Midpoint Formula to find the slope M first

Name the coordinates of both points x1 = -2, y1 = -6, x2 = 4,  y2 = 6

Plug them in the formula

M = y2 - y1/ x2 - x1

M =( 6 - 6)/( 4 - (-2))

M = 0/6

M = 0

Then use point slope formula

Plugin the slope M = 0 in the formula and pick one of the points above. Name the coordinates of  the point X1 = 4 and y1 = 6

y - y1 = m(x - x1)

y - 6 = 0(x - 4)

y - 6 = 0

y = 6

your equation is Y = 0x  + 6 but keep in this form y = b

The table gives the average number of days of rain in each month of the year. Find the median of the
given data.

Answers

Answer: 9.5

Explanation: The median of a data set is the middle number when all of the data points are ordered from smallest to largest. So for this data set, the first thing you want to do is put them in order from smallest to largest. That gives you:

6 6 7 7 7 9 10 10 10 10 11 12

Then we find the middle of the data set. Since there is an even number of twelve data points, it will be between the sixth and seventh point:

6 6 7 7 7 9 ^ 10 10 10 10 11 12

We take the average of those two in the middle to get the median: 9.5

The median of a data set is 9.5

How to find mean and median of a data?

Mean is the ratio of sum of the observations to the total number of observations.

Median is such a number for the arranged data set(ascending or descending order) such that to its left and to its right belong same number of observations.

The weight of meteorite A is 7 times the weight of meteorite B. If the sum of their weights is ​144 tons, find the weight of each.

Answers

Taking into account the definition of a system of linear equations, the weight of meteorite A and meteorite B is 126 tons and 18 tons respectively.

System of linear equations

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is, they must give the solution proposed in both equations.

Weight of each meteorite

In this case, a system of linear equations must be proposed taking into account that:

"A" is the weight of meteorite A."B" is the weight of meteorite B.

You know:

The weight of meteorite A is 7 times the weight of meteorite B. The sum of their weights is ​144 tons.

The system of equations to be solved is

[tex]\left \{ {{A=7B} \atop {A+B=144}} \right.[/tex]

It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, substituting the first equation in the second one you get:

7B + B= 144

Solving:

8B= 144

B= 144÷8

B= 18 tons

Remembering that A= 7B, the value of A is calculated as:

A= 7×18

A= 126 tons

Finally, the weight of meteorite A and meteorite B is 126 tons and 18 tons respectively.

Find the inverse of each function. Is the inverse a function? f(x)=1/4x

Answers

The Inverse of given function F(x) = 1 / 4x is F⁻¹(x) = 1 / 4 x

F(x) = 1 / 4x is a function of x.

Changing F(x) to the variable y

This means that F(x) = 1/4x becomes y = 1/4x.

Changing the variables x and y in the previously obtained equation

This means that we can deduce x = 1 / 4y from the equation y = 1 / 4x.

Solving the newly discovered equation for y

This means that we must simplify the equation by rearranging the terms in order to obtain the equation in terms of the variable x.

x =  1 / 4y

=> 4 y = 1 / x

=> y = 1 / 4 x

As a result, we obtain the required equation.

Switching the variable y with F⁻¹(x)

This assumes, y = 1 / 4 x becomes F⁻¹(x) = 1 / 4 x

Hence, the value of the given function F⁻¹(x) = 1 / 4 x

Write each equation in logarithmic form.
10³=1000

Answers

We get the equation in logarithmic form as log₁₀ 1000 = 3.

A “logarithmic equation” is an equation which involves the “logarithm” of any expression which is containing a variable.

Now, we have been given an equation:

10 ³ = 1000

We need to write it in the logarithm form.

We know that, it will be written as:

log₁₀ 1000 = 3

Since the power goes after the equal sign, so 3 is placed after the equal sign.

The actual value is taken after log, so 1000 is placed there and the base number is taken as the base for the log, so 10 is taken as the base for the log.

Therefore, we get the equation in logarithmic form as log₁₀ 1000 = 3.

What is the solution of 27³x=81 ?

Answers

Solution of exponential equation 27³x=81 is , [tex]x = \frac{1}{243}[/tex]

What is exponential equation ?

In, mathematics a exponential equation or exponential function is inverse of logarithmic function. That means, we can easily convert the logarithmic function into exponential function and vice versa. The basic form of the exponential function can be written as   .

   [tex]a^n = x[/tex]

where, a = the base of function

            x = main expression

            n = exponential

Mathematically, if  [tex]log_ax = n[/tex] is an logarithmic function then, this can be converted to exponential function as    [tex]a^n = x[/tex] .

There are many formulas that are given to us for solving several simple and complex problems based on exponential functions and exponential equations.

According to given statement,

27³ x = 81

divide both side by 27³ , the equation becomes :

[tex]= > x = \frac{81}{27^3} \\\\= > x = \frac{3^4}{(3^3)^3}\\\\= > x = \frac{3^4}{3^9}\\\\= > x = \frac{1}{3^5} = \frac{1}{243}[/tex]

LCM of 2 and 3 is 6
so, now we have to make denominators equal so we have to figure out much will we multiply with 2 and 3 to get 6 so,
1x3/2x3 + 1x2/3x2

(b) The distance between two towns on the map is 25 cm.
Find the actual distance, in kilometres, between the two towns.
(c) A lake has an actual area of 3.5 km.
Find the area, in square centimetres, of the lake on the map.
Give your answer correct to 3 significant figures.

Answers

We have been given that -

scale = 1:75000.

we have to find out

(a) scale expressed as 1 cm represents n km.

Map scale refers to the ratio between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground

so 1,00,000 cm = 1 km.

(b) given -

distance between two towns on the map is 25 cm.

Find the actual distance, in kilometres, between the two towns.

Scale is given as 1:75000

for 25 cm distance = 25×75000 cm

                              = 18,75,000 cm

therefore 1875000 cm = 18.75 km.

the real distance between two points is 18.75 km.

(c) . The area of the lake in the real world is 3.5 square kilometers.

1 square kilometer is equal to 1 kilometers squared.

since 1 kilometer is equal to 100,000 centimeters, then 1 square kilometer is equal to 100,000^2 centimeters which is equal to 1 * 10^10 square centimeters.

3.5 square kilometers on the map is therefore equal to 3.5 * 10^10 square centimeters.

1 centimeter on the map is equal to 75000 centimeters in the real world.

1 square centimeter on the map is equal to 75000^2 centimeters in the real world which is equal to5625 * 10^6 square centimeters in the real world.

take 3.5 * 10^10 square centimeters in the real world and divide it by 5625 * 10^6 square centimeters and you get .0006 * 10^4 square centimeters which is equal to 6 square centimeters on the map.
